Cal Piker hasn’t seen his sister Samantha since their mom’s funeral, so when he interrupts her English lecture one morning with a proposal - every week out within the woods of Oregon, in search of Bigfoot within the legendary 'Ape Canyon' - she is greater than a bit stunned. But it surely’s a harmful factor to be led round by Cal, an irresponsible, frustratingly likable child brother, enthusiastic to the purpose of irrationality to search out Bigfoot for himself. For Cal, this isn't a matter of legend. This isn't just a few journey. If Samantha doesn’t cease him, Cal will both discover Bigfoot or die attempting.
